yes , you can take whatever portion of your aftertax principal that they'll let you have before they start making you also take some beforetax stuff along with it .
you don't ever have to worry about being taxed twice . they'll keep it straight for ya . keep in mind that it's only the aftertax principal that you've already paid taxes on . don't forget you also have all those years of deferred earnings on those aftertax dollars that you still have to pay taxes on .
putting a control on your income is always a good idea and one of the nice things about being retired . i personally use a " bucket " strategy wherein i use a bucket number one for everyday living expenses . i keep these funds separate from my other investment portfolios and at this time it consists of several year's worth of living expenses ( one to two hundred thousand or so ) in a tax free money market account . i write myself checks from this account to cover every day living expenses . this prevents me from having to make " sell " decisions based on the fact that I might need money when the market isn't right to pull money from at that point in time . clayton has been particularily good about putting himself in the lowest tax bracket every year so you'll have to talk to him about the ins and outs about it . I personally am involved in a ROTH conversion program and therefore put myself in a higher tax bracket every year than i need to in order to exist in order to convert dollars every year to ROTHs . it's just a different strategy and generally only necessary for those who will find themselves in a much higher tax bracket in later years . if i don't do ROTH conversions now , after required minimum distributions begin at age 70 1/2 , i will find myself in the highest tax bracket forever . for more details on this and other retirement planning , pick up a copy of the I.R.S. publication 590 . it's the retiree bible .
call hewitt / xerox and talk to them about what you're thinking . they're pretty good about helping you decide what to do . at least give you all your options to consider .
and , of course I know you already know big " O " , but for those others that also read these personal messages that might think that i might actually know what I'm talking about I have to put out this warning that this isn't specific investment advice from myself , xertech , or yourself . that this is strictly for educational purposes only . and that each person needs to consult his or her own investment advisor for specific advice . after all , your money is yours and my money is mine . to have and to lose .
